Description
Technical field
The utility model belongs to freeze-drier technical field, relates to the sampler of vacuum freeze, particularly relates to a kind of separation valve door of freeze-out sampling device.
Background technique
Vacuum freezing drying, also referred to as freeze-drying, is a kind of technological method of material drying, is generally used for the medicine of sterile preparation class or the drying of biologic product.In this freeze-drying process, material is first frozen, then under vacuum conditions by the moisture in distillation and desorption removal material, makes moisture reduce to degree required for storage.The freeze-drying of the material flaggy normally in freeze-drying tank completes.In order to study the rule of the freezing and crystallizing of material in freeze-drying process, lyophilization and adsorption stripping and dry, and in order to explore more suitable freeze-dry process technology, people need often directly to observe the material be in freeze-drying process and measure, thus need to take out bottled material from the flaggy in freeze-drying tank in freeze-drying process.This bottled material be removed is commonly called freeze-drying sample.Can not affect the special purpose device of other material continuous freeze-drying process in freeze-drying tank when taking out freeze-drying sample, being commonly called sampler.
Sampler is under normal circumstances generally containing sampling container, sampling bottle clamp device, tamponade device and sampling separation valve door.Wherein, sampling container is used for the pressure condition that provides for sampling operation and clean environment; Sampling bottle clamp device is for the freeze-drying sample that clamps in freeze-drying tank on flaggy and moved in sampling container; Tamponade device closes freeze-drying sample for the plug on bottleneck being pressed into completely bottleneck; Sampling separation valve door is used for the local of sampling container or all carries out seal isolation, working pressure when to take out freeze-drying sample at sampling container or its local recovery's normal pressure to ensure in freeze-drying tank is constant, thus does not affect other material continuous drying under vacuum conditions.
At present, the structural type of sampling separation valve door mainly contains two kinds, the first is take application number as the Chinese invention patent of CN201210201637.8 is representative in the inner structural type of sampling container being carried out to local isolation of sampling container, and the second is, and to be representative with the application number Chinese utility model patent that is 200520016602.2 carry out completely isolated structural type at the jointing of sampling container and freeze-drying tank to sampling container.The first form adopts the local of this body structure to sampling container of sample lifting device to isolate, thus in sampling process, realize the isolation of vacuum environment and atmospheric pressure environment, but this structural type can not eliminate sampling bottle clip and sample lifting device produces the impact of Leakage Gas due to straight line motion, if the seal failure at this straight line motion position, the failure of whole freeze-drying process also can be caused.The second form is between sampling container and freeze-drying tank, installed common vacuum gate valve, although the isolation of vacuum environment and atmospheric pressure environment can be realized in sampling process, also the Leakage Gas impact that sampling bottle clip produces due to straight line motion can be eliminated, but the sterility requirements to device structure when the internal structure of conventional vacuum push-pull valve is difficult to medicine or the biologic product drying meeting sterile preparation class.
Summary of the invention
For the deficiency that the separation valve door overcoming existing freeze-out sampling device exists, the utility model provides a kind of separation valve door of freeze-out sampling device.
Separation valve door described in the utility model comprises: valve plate, lifting push rod, axle sleeve, connecting rod, eccentric hoop, back-up ring, spring collar, central shaft, rotatingshaft, bearing support, bearing, sleeve pipe, hand handle, sampling container, valve port; Wherein, be connected by pin between valve plate with connecting rod; Lifting push rod is fixedly connected with by pin with axle sleeve, sets gradually central shaft and pad in axle sleeve; Eccentric hoop and central shaft are fixed by pin, central shaft is arranged on connecting rod, the top of central shaft is inserted and is fixed on the bottom of rotatingshaft, rotatingshaft loads bearing support, rotatingshaft sets gradually bearing, sleeve pipe and hand handle, sleeve pipe is fixedly connected with by major part screw with bearing, and handle is fixed by screws on sleeve pipe; Bearing support and sampling container are connected by screw fixing; Valve port is arranged on the side of valve plate.
Further, small end described in the utility model sets gradually back-up ring and spring collar.
Further, valve port described in the utility model is arranged sealing valve port groove, sealing valve port circle is set in sealing valve port groove.
Further, stuffing box packing is loaded between rotatingshaft described in the utility model and bearing support.
Further, the top shape of central shaft described in the utility model is that in-line is protruding, and it is the protruding corresponding Baltimore groove of in-line that the bottom of rotatingshaft is arranged to described shape.
For ease of understanding further and operating the utility model, the operating method of described separation valve door is as follows:
Step 1, when described separation valve door closed by needs, is upwardly elevated push rod, with the top making valve plate rise to sampling container;
Step 2, rotate hand and drive central axis making rotatingshaft, eccentric hoop drivening rod and valve plate produce lateral displacement, thus valve plate and sealing valve port circle are fitted;
The step 3 then fastening major part screw of manual rotation makes valve plate and sealing valve port circle keep fit-state, completes the closedown of separation valve door;
Step 4, when described separation valve door opened by needs, to outward winding major part screw, rotate hand handle, to make rotatingshaft drive central axis, be now installed on eccentric hoop drivening rod on central shaft and valve plate produces lateral displacement, thus make valve plate be separated with sealing valve port circle and produce gap, then pull lifting push rod to make central shaft and rotatingshaft realize being separated downwards, and make valve plate drop to the bottom of sampling container, complete the unlatching of separation valve door.
Compared with prior art, the utility model has following beneficial effect:
1, the separation valve door of freeze-out sampling device described in the utility model is applicable to the sampler of vacuum freeze, separation valve door of the present utility model is have employed between freeze-drying tank and sampling container, the isolation of vacuum environment and atmospheric pressure environment can not only be realized in sampling process, and the impact of sampling bottle clip due to straight line motion generation Leakage Gas can be eliminated, eliminate because the seal failure of straight line motion position causes the hidden danger of freeze-drying failure, the internal structure solving conventional vacuum push-pull valve can not meet medicine or the dry problem to device structure sterility requirements of biologic product of sterile preparation class.
2, the structure that the utility model provides has isolates reliable, application advantage widely, not only meets the sampling process isolation of experiment vacuum freeze, can also meet the isolation of the sampling process of production vacuum freeze.
